Question

Fac-mer isomerism is associated with which one of the following complexes? (A) [M(A A)2] (B) [M A3 B3] (C) [M(A A)3] (D) [M A B C D]

The compounds of the formula [ MA 3 B 3] exhibit fac and mer isomerism. The fac isomer is also known as facial isomer or cis isomer. Three A ligands are present on one triangular face and three B ligands are present on opposite triangular face. The mer isomer is also known as meridional isomer or trans isomer. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/dd74610c0c20373191f469bd19998030-.png" />
